Definitions

  • the present invention relates to the use of a device for separating oil and water in a vacuum container into which the fluid mixture is dusted by means of an adjustable truncated cone round jet nozzle.
  • the document US 4,392,874 A describes a device for degassing liquids by generating a liquid film.
  • the document GB 982598 A describes spray nozzles for car washes.
  • the inflowing fluid mixture is atomized conical, the cone preferably opens upwards.
  • An inlet pump sucks the fluid mixture, in particular oil / water mixture, via a suction screen and presses it via the abovementioned adjustable truncated cone round jet nozzle into the vacuum container.
  • the tube acting as a nozzle holder is introduced with the truncated cone round jet nozzle from above into the vacuum container.
  • the nozzle holder would have to be correspondingly angled.
  • the device described also contains a liquid outlet in the bottom area, through which the dried fluid, for example the dried oil, can be removed.
  • the vacuum container will contain a level measuring device, which may be realized for example via one or more floats.
  • a level measuring device which may be realized for example via one or more floats.
  • the fluid can be removed by pumping out of the liquid outlet, while the pump is switched off when the minimum level is reached. In normal operation, an attempt is made to set the pump outputs so that the level stagnates approximately in the middle range.
  • the vacuum container includes a gas outlet for evacuation of the system.
  • the gas outlet is connected to a vacuum pump which produces the necessary negative pressure (-0.9 to -0.2 bar, preferably -0.9 to -0.5 bar) set in the vacuum vessel and, for example, via a coalescing filter and a silencer Promoted outside.
  • a coalescing filter and a silencer Promoted outside e.g. a carbon filter are downstream, which is, however, usually unnecessary, because the exiting air through a coalescer usually contains an oil content of less than 5 ppm.
  • the vacuum chamber contains a controllable gas inlet. During operation, this gas inlet always introduces a controlled amount of gas into the vacuum chamber.
  • the gas is preferably ambient air, which in principle requires no change.
  • the incoming air is directed, for example via an air filter with 10 micron filtration and a diaphragm with a defined aperture bore of about 5 mm and a downstream throttle check valve in the vacuum vessel.
  • the air can be treated before entering the vacuum chamber, for example dried. Pre-drying may be recommended in cases of high humidity, especially if a high degree of drying is achieved in the separation process should.
  • low-oxygen gases may be added (or mixed in), for example nitrogen, argon, carbon dioxide, especially in the separation of (highly) flammable fluids.
  • both nuts have the same outer diameter.
  • the height of the nuts is largely without influence on the separation result. It depends mainly on the geometric conditions of the tube and can be determined by a person skilled in the art without further inventive step.
  • Both nuts are secured in a preferred embodiment of the invention by corresponding lock nuts.
  • the gap width is variable in a simple manner.
  • the gap width can therefore be easily adapted to different fluid mixtures, flow rates or other process parameters (temperature, pressure, fluid viscosity).
  • the gap width can be selected between 0.01 and 10 mm, preferably between 0.5 and 1.5 mm.
  • the cone angle ⁇ also depends on the parameters mentioned above, in particular the type of fluid mixture and the process parameters.
  • the angle ⁇ can be set between 10 ° and 80 °, preferably values between 45 ° and 80 °.
  • the described nozzle is readily scalable, so that it can be adapted for correspondingly larger-sized devices.
  • a pipe diameter of about 45 mm With a pipe diameter of about 45 mm, a throughput of 25 to 70 L / min of an oil / water mixture can be achieved.
  • An important aspect of the invention is therefore a truncated cone round jet nozzle (K) for nebulization of fluids, consisting of a tube (R) with a closed end (E), wherein the tube has a tube taper in front of the closed end (E), wherein the Tube taper limits the diameter of the tube to 90-30% of the input diameter (R D ), 2-8 orthogonal to the flow direction (SR) in the region of the tapered holes (L) as outlet openings, wherein the holes each have a diameter (L D ) between one-twentieth and one-half the pipe diameter at the tapered location (R J ), a first union nut (M1) having an outside diameter of 1.25 - 2.5 times the pipe diameter at the tapered point (R J ) with shoulder-shaped taper, wherein the shoulder has a height (M 1H ) of 0.1-10mm and a width (M 1B ) of 90-70% of the original diameter, a second cap nut having an outside diameter v 1.25
  • the device optionally also includes a tilt damping of the float.
  • This inclination damping device consists essentially from a central tube in which the float can move. This tube is open at the bottom and at the top so that the fluid tube contents interact with the total fluid of the vacuum container contents. Said device results in that the inclination of the overall device, as may occur, for example, in shipping, the float deviates only slightly from the respective filling position in a straight line and thus can reliably perform said pump circuits.
  • This damping device is extremely important, for example, in seafaring, when it comes due to high sea state to tamping and rolling movements of the ship and the device thereon. In test it could be shown that the function of the plant is fully maintained even at roll degrees of 15 ° to both sides.
  • FIG. 5 and 6 such a tilt damping device is shown.
  • the floats each have an upper and lower stop (S O1 , S O2 , S U1 and S U2 ).
  • the position of the floating body can be determined, for example, via a magnetic marking in conjunction with a corresponding reed contact.
  • other embodiments are conceivable, for example, also on an optoelectronic basis.
  • the desired level in normal operation between the upper stop of the lower float (S O1 ) and the lower stop of the upper float (S U2 ) see Figures 5 and 6 ). In this desired normal operation, therefore, both floats remain on the aforementioned attacks. When this condition is exited (by lowering or increasing the level), appropriate controls on the pumps can intervene to return to normal operation.
  • the vacuum pump is first started, which evacuates the vacuum chamber.
  • pressures of -0.9 to -0.2 bar, preferably -0.9 to 0.5 bar are set.
  • the inlet pump delivers the oil into the vacuum tank until the level float starts the outlet pump. This conveys the dried fluid collected in the bottom of the vacuum container into a container.
  • the fluid is recirculated, that is, the separated (eg, dried fluid) is returned to the intake location (e.g., an oil reservoir).
  • the fluid mixture is an oil / water mixture
  • temperatures between 40 ° and 70 ° C are set.
  • the mixture is injected into the vacuum vessel via the above-mentioned truncated cone round jet nozzle, wherein the water droplets contained pass into water vapor.
  • This water vapor is sucked in together with the air flowing in through an air filter from the vacuum pump and conveyed through a coalescer filter and a silencer to the outside.
  • a carbon filter can be connected downstream, which is, however, usually unnecessary, because the exiting air through the coalescer filter usually contains an oil content of ⁇ 5 ppm.
  • the inflowing air is directed via an air filter with 10 micron filtration and a shutter with a defined orifice bore of about 5 mm and a downstream throttle check valve in the vacuum vessel. Due to the heat introduced with the fluid, a temperature is reached within the vacuum vessel, which enables the ambient air to absorb the water vapor.
  • the nozzle shape makes it possible, among other things, to dry motor oils, and the drying of diesel oil is also possible.
  • the device described can be used in various fields of technology, for example in power plants, industrial companies, sea and airships, vehicles and aircraft.
  • the device is preferably used for drying oils, for example hydraulic oil, lubricating oil, gear oil, engine oil, turbine oil and / or diesel oil.
  • the device according to the invention is characterized by a compact size and is significantly less susceptible to dirt.
  • a device according to the invention overcomes a prejudice in the art, as for example in the DE10024124C1 (See paragraph 0006):
  • devices for separating water from oil where the oil is atomized by means of a nozzle in a vacuum chamber, are associated with some disadvantages, such as reintroduction of air and water into the oil , a susceptibility to fouling and uncontrollable foaming.
  • These prejudices can be refuted by the device according to the invention, in which it does not come to the disadvantages described even with prolonged operation and soiled and / or highly viscous oils.
